SPECIFICATION forming partefA Letters Patent NO. 706,105, dated August5, 1902. Applicationlil'ed December 22,1900. VSerialNo. 40,830. (Nomodel.)

ship of Vestern, county of Oneida, and State of New York, have inventeda new and useful Driving Mechanism for I-Ioistingand Carryin gApparatus, of which the following is a speciiication. n

This invention relatesto the art of loading and unloading, and has forits object to provide an improved driving mechanism for hoisting andcarrying apparatus which is under the control of a single attendant, sothat I5 the hoisting and carrying operations may be independentlycarried on Without stopping or reversing the engine employed for theoperation of the apparatus. signed to arrange for bringing the apparatus2o to a complete stop when changing the direction of operation thereofand when changingfrom the hoisting to the traveling operation;

and vice versa, so that there may be nosudden reverse movements tointerfere withthe proper operation of the apparatus or to in jure thesame in any manner.

A final object resides in the provisionof means whereby the apparatus iseffectively locked against accidental operation during a 3o period ofinaction, although the engine may continue to operate, so that theapparatus may be quickly thrown into operation for either purpose and ineither direction of motion.

lVith these and other objects in view the I present invention consistsin the combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings, and particularly 4opointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claims without departing from the'spirit or sacrificing anyof the advantages ofthe invention.

In the drawings, Figure 1 is a side 'elevation of the controllingportion of the apparatus. Fig. 2 is a detail sectional elevationthereof. Fig. 3 is a broken front end view.

5o Fig. fiis a broken top plan view. Fig. 5 is a It is furthermorededetail elevation of a drive-pulley and the adj acent friction-pulley.Fig. 6 is a detail sectional elevation lof the clutch for locking thedrum that operates the traveling portion of the cable. Fig. 7 is adetail sectional view of the clutchmechanism.

Like characters of reference designate corresponding parts in all of thegures of the drawings.

In-carrying out the invention there is provided a frame for the supportof the controlling mechanism consisting of a pair of parallelbase-sills, one of which has been illustrated at 1 and from the oppositeends of which rise the corner-posts 2, which support the longitudinalframe-beam 3, located a suitable distance above the sill and paralleltherewith. As shown in Fig. 4 of the drawings, the opposite longitudinalbeams are connected at opposite ends by means of the respectivecross-bars 4, and thereby completing the supporting-frame.

A pair of transverse rotatable shafts 5 and 6 are mounted upon the sidebeams, the front shaft 5 being journaled upon the tops of the beams, asat '7, and the rear shaft 6 upon the under sides of the said-beams, asat 8, whereby the forward shaft is slightly elevated above the othershaft. These shafts are provided with the respective drums 9 and 10,which terminate short of one of the side beams for the accommodation ofthe intermeshed gearwheels 11 and 12, carried by the respective shafts.The gear 1l is loosely mounted upon its shaft, while the gear 12 isfixed to rotate with its' shaft, there also being a broad-facedfriction-wheel 13 fixed to the shaft 6 and located between the gear 12and the adjacent side beam 3. 1t will be understood that the drum 10 isdriven by the friction-Wheel13, and the drum 9 is simultaneouslyoperated in the opposite direction through the medium of the intermeshedgears 11 and 12, whereby as the cable portion 14 is being wound upon thedrum 10 the opposite cable portion 15 is being unwound from the oppositedrum 9, and vice versa, thus to accommodate for the opposite directionsof travel a'suitable carrier, not herein illustrated.

The drum 9, which will be termed the trav- IOO eling drum, is designedto move the carrier, and the other or hoisting drum is designed toperform the hoisting operation, and in order that the last operation maybe accomplished while the carrier is at rest it is necessary to throwthe traveling drum out of operation during the hoisting operation. To

accomplish this result, a clutch device is provided for theloosely-mounted gear 11, consisting of a disk 16, slidably mounted uponthe shaft 5 and located between the gear 11 and the adjacent side beam3, said disk being held against rotationu pon the shaftby means of a keyor feather 17. The outer side of the disk is provided with a pair oflateral projections 18, which are designed to take into correspondingnotches or sockets 19 formed in the inner face of the adjacent side beam3, thereby to hold the shaft against rotation, and as the gear 11 isloosely mounted upon the shaft and is free from the traveling drum theshaft and the latter remain idle during the hoisting operation of thehoisting-drum. The opposite inner side of the disk 16 is provided with asocket, one or more, for the reception of a lateral'projection, one ormore, 20, upon the outer face of the gear 11, whereby the gear may beinterlocked with the shaft 5 to operate the same and the drum 9, whichis fixed thereto. For the convenient manipulation of the clutch to slidethe same in opposite directions upon theshaft for alternate engagementwith the frame and the gear there is provided an operating-lever 21,which is fulcrumed intermediate of its ends upon a suitable bracket 22,provided upon the inner side of the adjacent post 2, the upper end ofthe lever being provided with a fork 23 to loosely embrace the lowermarginal edge portion of the clutch-disk. A band 24 loosely embraces themarginal edge of the disk and is provided with diametrically oppositepivot projections 25, which are snapped into terminal perforations inthe fork of the lever, whereby the latter is connected to the clutchdiskand the latter may be slid in opposite directions upon the shaft bymanipulation of the lower free end of the lever.

Normally to hold the drum against accidental operation there is provideda frictionbrake, consisting of a brake-lever 26, fulcrumed at its outerend upon the rear cornerpost 2, which is adjacent to the friction-wheel13 and projected above the top of the frame, so that the outer free endof the lever may lie at the outer side of the wheel and adjacent to theupper portion of said wheel. A brake-shoe 27 is projected laterallyinward from the free end of the lever, so as to lie in frictionalengagement with the marginal edge of the wheel. A link 28 is pivotallyhung from the outer side of the free end of the brake-lever, and at thelower end of this link there is suspended asubstantially horizontalrocker-bar 29, which is pivotally connected at its middle to the lowerend of the link. This bar lies immediately over and parallel with theadjacent base-sill 1 and just out of contact therewith, so that itsweight is supported by the brake-lever, thereby normally drawing thebrake-shoe into frictional en- `gagement with the friction-wheel for thepurpose of holding the same and the drums against accidental rotationwhen the entire device is at rest.

For conveying power from an engine (not shown) to the friction-wheel 13,which is really the power-wheel of the apparatus, the opposite ends ofthe rocker are provided with the respective stub-shafts 30 and 31, whichproject at opposite sides of the rocker, as best shown in Fig. 5 of thedrawings, and are provided upon their respective outer ends with thedrive-pulleys 32 and 33 and upon their inner ends with thefriction-pulleys 34 and 35, shown in Figs. 4 and 5 and designed foralternate frictional engagement with the friction power-wheel 13 byrocking the rocker- `bar 29 upon its pivotal` connection with the link28. A continuous drive-belt 36 comes from an engine and passes from thefront to the rear of the apparatus, around the drivepulley 32, from thetop thereof, thence forwardlyand around the top of the drive-pulley 33,thence rearwardly and around an idle pulley 37, mounted upon the outerside o t the adjacent base-sill 1,V and finally back to the engine. Bythis arrangement of the drivebelt the drive-pulleys are driven inopposite directions, as indicated by the arrows in Fig. 2 of thedrawings, whereby said drive-pulleys are adapted to drive thefriction-wheel 13 in opposite directions when alternately appliedthereto, thus reversing the direction of rotation of the drums withoutstopping and reversing the engine.

A To facilitate the rocking of the rocker-bar 29 to alternately bringthe friction-pulleys into engagement with the powerwheel, there areprovided duplicate means for elevating the respective ends of therocker, each of said means consisting of a lever 38, which is fulcrumedintermediate of its vends, as at 39, to the outer side of the adjacentbase-sill and substantially parallel therewith and also between thelatter and the adjacent drivepulley. The inner end of the lever isprovided with a pendent rope 40, forming means for conveniently throwingthe lever, while the opposite free end thereof is provided with alateral spindle or projection 41, that lies between the base-sill andthe adjacent end portion of the rocker, there being a suitableantifriction-roller 42 mounted upon the spindle and lying within asuitable socket formed in the top of the sill, so that by depressing theinner end of the lever the roller42 will be thrown upwardly against therocker-bar 29 for the purpose of Velevatin g the adjacent end thereof,and thereby bring the adjacent friction-pulley into engagement with themarginal edge of the friction-wheel13. It will be understood that thelower side of the rockerbar is bowed or beveled upwardly in opposite IOOIIO

directions from its center to accommodate for the rockingaction thereof.

It will be apparent that it is necessary to raise the brake-shoe out ofengagement with the friction or power wheel 13 when the friction-pulleysare applied thereto, and to provide for this release of the brakesimultaneously with the application of either frictionpulley theopposite end portions of the rocker are provided with the respectivelateral outwardly-directed studs or projections 43, that normally lieabove and out of contact with the top of the base-sill, there beingopposite upstanding guides 44, rising from the sill and lying closely atopposite sides ot' the projection, so as to guide the rocker in itsvertical movement. When one end of the rocker is elevated, the oppositelateral projection 43 will movedownwardly and strike the top of thesill, thereby acting as a fulcrum for the rocker, whereby the middleportion thereof will be slightly elevated, thus pushing the link 28upwardly and lifting .the brake-lever 26, lthereby removingthebrake-shoe 27 from the friction-wheel 13, so that the latter may beturned by the friction-pulley. When the reversing-lever is permitted toreturn to its normal position, the rocker will also resume its originalposition, thereby drawing the friction-pulley from the drive -wheel andagain applying the brake, whereby the apparatus is brought to a completestop before the other reversing-lever can be manipulated to reverse thedirection of operation of the apparatus. Thus the apparatus is normallylocked by the brake against accidental operation, and the brake isautomatically applied during the intervals between the reversings ofdirection of operation.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, isy l. In a reversing apparatus, thecombination of a power-wheel, a brake normally applied thereto,oppositedrive-wheels supported by the brake and constructed for alternateengagement with the power-wheel, and means for automatically removingthe brake by the application of either drive-wheel.
